Abstract: 377,674. Ratchet mechanism ; automatic regulating devices. SANDISON, A. G. S., Kelda, Baltasound, Shetland Isles, and INDUSTRIAL COMBUSTION ENGINEERS, Ltd., Cecil Chambers, Strand, London. Feb. 27, 1931, No. 6175. [Class 80 (iii).] Automatic control mechanism for regulating the value or supply of such quantities as temperature, electric current or voltage, and pressure or flow of fluids, for example, the draught suction or vacuum in the air passages of a boiler installation, comprises a wheel 6, which is normally idle, pawls 9, 22 or rocking arms 3 one on each side of the wheel, and means to engage the pawls with the wheel when a control member 33 with graduated engagement is moved sufficiently away from normal position. The wheel 6 is fast on a shaft 5 geared to a device which regulates the value concerned. Weighted tliree-armed levers 11 are pivoted about the shaft 5 and are linked to bars 18, 31 formed with stepped projections 21, 32. Normally arms 12 press against fingers 13 on the pawls and hold the latter away from the wheel. The arms 3 are continuously rocked by means of a rotating crank 1 and rod 2. If the member 33 moves up or down to interfere with the motion of either bar 18 or 31 the motion in one sense of one of the arms 12 is stopped and the corresponding pawl engages and rotates the wheel 6 to alter the supply. In a modified construction, Fig. 4, pawls 64, 66 are carried by oscillating plates 59, one on each side of the wheel, and are biassed towards the wheel by a spring 81. Rockers 71, 72 are mounted frictionally on a spindle 68, the pawls being normally held out of engagement by arms 77, 78 on the rockers. If the motion of the bars 18, 31 is interfered with by a block 94 a pawl is freed from the influence of one of the arms 77, 78 and moves the wheel as described above. The stepped portion of the bars 18, 31, Fig. 1, may be formed on threearmed plates frictionally pivoted to the bars.

Title: Improvements in methods of and apparatus for the treatment of molten iron and steel
IPC: C21C1/10
Filed: 1955-03-02
Abstract: 765,423. Making additions to iron and steel. MOND NICKEL CO., Ltd. March 2, 1955 [March 6, 1954; Jan. 27, 1955], No. 6191/55. Classes 72 and 82(1) An addition agent of lower boiling point than iron is introduced into molten iron or steel by placing the addition agent and a container of the molten metal separately into a pressure vessel, introducing a compressed gas into the pressure vessel to raise the pressure to a value at least equal to the vapour pressure of the addition element at ' the temperature within the vessel and mixing the addition element and the molten metal with vigorous stirring whilst maintaining the pressures. More than one addition element may be added, the pressure then being kept above that of the addition element having the highest vapour pressure. In the apparatus for treating iron with magnesium shown, a ladle 48 containing the iron is placed within the pressure vessel 6, the lid 11 of the vessel mounted in a framework 12 is swung into position and the vessel is raised by the hydraulic ram 4 to force it against the lid. Air is expelled from the pressure vessel through a cock 41 by argon from a cylinder 32, the cock 41 then being closed and the pressure allowed to build up to the desired value. An openwork container 20 holding the magnesium is then lowered into and reciprocated in the iron by a compressed air piston 10. When the mixing is complete, a valve 31 in the argon supply line is closed and the cock 41 opened to allow the argon in the pressure vessel to pass into a low-pressure gas reservoir 44. The cock 41 is then closed again and the pressure vessel opened and the ladle removed. The argon in the reservoir 44 may be compressed by a compressor 38 for re-use. In other forms of apparatus described the magnesium may be added to the iron by (1) lowering an openwork container into the iron and stirring the melt by induction, (2) lowering the container into the iron and rotating it to cause stirring. (3) pouring the iron from an upper ladle on to the magnesium in a lower ladle, or (4) supporting the magnesium on a disc which is then reciprocated in the iron. The upper part of the pressure vessel may be lifted by a crane and lowered in turn on to a number of bottom parts and the vessel may be pressurized by compressed air.

Filed: 1937-03-02
Abstract: 491,503. Milling &c. cutters. WEDDELL, R. R. March 2, 1937, No. 6222. Convention date, Dec. 18, 1936. [Class 83 (iii)] A milling or like rotary cutter of the kind having a blade and a wedge side by side in a slot in the body has the blade in contact with a side wall and the bottom of the slot and the wedge tapered transversely and engaging a side wall of the slot through interfitting serrations so that the blade may be adjusted longitudinally in the slot to set two cutting edges simultaneously. In a face milling cutter the slots 12 are formed in a projecting flange 11 of the body 10 and converge inwardly towards the cutter axis, and transversely at an angle alpha, Fig. 8. The blades 13, which may be made from the alloy sold under the Registered Trade Mark " Stellite," have plane surfaces 24, 25, tapering longitudinally and transversely, and cutting edges 15, 16. Adjustment of the blades is effected by sliding them along the bases 21 of the slots which are inclined at the angle requisite for moving the cutting edges 15, 16 in the desired proportions and locking is effected by wedges 14 which are tapered both longitudinally and transversely and have serrations engaging serrations 18 in the slots. As the blades are adjusted outwardly after grinding, as shown in Fig. 7, the wedges are set inwardly by engaging different serrations so that the outer edges 30 of the wedges will always be adjacent the cutting edges of the blades, recesses 19, Fig. 8, being provided at the bases of the slots to accommodate the wedges in their' innermost positions. The transverse taper of the blades is formed symmetrical, as shown by the angles a, Fig. 8, in order that cutting edges may be ground on either side to adapt the blades for use in bodies arranged for clockwise or counterclockwise rotation, the serrations being provided on the wedge sides of the slots in each case.

Title: Improvements in or relating to electrical selecting arrangements for controlling the connection of individual to common apparatus
IPC: H01H67/24
Filed: 1931-02-28
Abstract: 370,141. Totalizators. ERICSSON TELEPHONES, Ltd., 67, Kingsway, Lon. don, and WILMAN, C. W., 7, Grange Avenue, Beeston, Nottingham. Feb. 28, 1931, No. 6305. [Class 106 (i).] For the selective connection of individual ticket-machines with the common equipment by means of a series of relays, the arrangement is such that current flows ineffectively through the windings of non-selected relays but effectively through the winding of the particular relay required. Thus as shown in Fig. 1 the relays A1 .. A5 are provided with opposed windings and by the closure of a contact B1 .. B5 one winding of the corresponding relay is earthed to cause the relay to operate, the relays to the left being unaffected and those to the right short-circuited. To maintain the chain, even when certain relay connections are broken, each relay may have its windings shorted by equivalent resistances as shown in Fig 2. In another arrangement, Fig. 3, the individual relay may be shunted by one winding of a relay F normally inoperative. If the relay connections are broken this relay operates and locks up, thus removing the earth at F3 and providing a through path at F1. Fig. 4 shows the invention as applied to the arrangement described in Specification 368,445. The setting-up of a bet applies earth at st3 to the relay in question so as to operate relay A which then functions as stated in that Specification, and at a3 breaks the earth connection to allow other machines to be connected. Re-connection of the first machine before the others have been attended to is prevented as in the prior case by a holding-off relay and the circuit of this relay may be prepared by a contact of a relay inserted at the earthed .end of the relay chain. In another arrangement, Fig. 5, utilizing the invention of Specification 371,101, t h e ticket machines are grouped in " rows and the selection of the various rows and the separate machines is effected by chains of relays. Thus operation of relay ST (not shown) at a particular machine extends earth at st1 to relay SA of the vertical chain CT to CD and this in turn energizes the chain AX .. AN of the top row of machines to operate at ax1 the connecting relay A of the machine in question. The holding-off circuit is prepared at cd1 as before, by the shorting of relay CD. Other arrangements of the chain relays are shown in Figs. 6 .and 7. In Fig. 6 the contact B1 .. B5 - short-circuits one winding by connecting the - other directly to the line and in Fig. 7 the relays are connected up in a closed chain and the closure of a contact B1 .. B6 causes current to flow in the same direction through both windings of the relay concerned.

Title: Improvements in or relating to catalyst manufacture
IPC: B01J37/02
Filed: 1954-03-04
Abstract: Catalytic inorganic oxides, such as alumina and magnesia, or mixtures of oxides, such as silica-alumina, beryllia-alumina, thoria-alumina, magnesia-beryllia, are subjected to a particle size reduction, such as by a severe wet grinding operation in aqueous medium, until when in admixture with an approximately equal weight of water said oxides form a mass of viscous consistency which remains substantially homogeneous on prolonged standing.  The oxide is suspended in a liquid vehicle, contacted with an inert support, such as porcelain, to deposit thereon a thin film of the oxide after the manner described in Specification 693,178 and may be further modified by impregnation with a small quantity of platinum before drying. The liquid vehicle may be an aqueous solution of metal salt which on heating decomposes to give a superficial film of metal oxide on the catalytic oxide film, e.g. with silicaalumina a slurry in an aqueous solution of aluminium nitrate is used.  The oxides are preferably activated before particle size reduction. Specifications 690,825 and 697,551 also are referred to.

Filed: 1925-03-10
Abstract: 233,663. Schmidt'sche Heissdampf- Ges. May 7, 1924, [Convention date]. Addition to 231,451. Controlling-Apparatus, arrangements of hand or trasmission gear in conjunction with; controlling different functions by same lever; automatic power control.-Relates to locomotives as described in the parent Specification, comprising two or more steam generators working at different pressures and supplying steam to different stages of an engine, the regulators or stop valves of the separate generators being controlled by a single operating means which may be actuated by hand or automatically. According to the present invention additional hand or automatic control is superposed at certain times, as at starting or stopping, on the automatic control, so as to alter the steam distribution at those times. In the construction shown, two regulators (not shown) are operated by cams 15, 16 carried by a sliding sleeve 38 splined on a hand-controlled shaft 13, so that when this shaft is rotated the regulators are opened or closed, their relative openings depending on the position of the sleeve 38. This sleeve is moved axially by a piston 41 acted upon by a spring 43 and also at 44<1> by steam from the low-pressure generator. So far, the apparatus is as described in the parent Specification. The additional control comprises a larger piston space 42 acted upon by the exhaust steam. As at starting the exhaust steam pressure is higher than the normal, due to the later cut-off, the steam pressure on the piston 41 is greater at starting and thus the sleeve 38 is moved to the left, causing a greater proportion of steam to be taken from the low-pressure generator. A hand-controlled valve may be provided in the exhaust steam supply pipe. In a modification the piston 41 is simply acted upon by the low-pressure steam and the spring 43, the pressure of the latter being adjusted, when desired, by the driver.
